Explanation

Buccal administration specifically refers to placing medication in the buccal pouch, which is the space between the cheek and the gum.
This route allows the medication to dissolve and be absorbed directly through the mucous membranes into the systemic circulation.
It offers rapid onset of action and bypasses the gastrointestinal tract and first-pass metabolism in the liver, which can inactivate some drugs.
Patients should be instructed to alternate cheeks with each dose to prevent mucosal irritation and to not chew, swallow, or drink fluids while the medication is dissolving.

Option A: This route involves placing medication under the tongue, not between the cheek and gum.
Option C: This is an injection into the dermis layer of the skin, not a route within the oral cavity.
Option D: This involves applying a patch to the external skin surface for slow, prolonged absorption.

Visual 1: Diagram: An anatomical illustration clearly showing the placement of a tablet for buccal administration (between cheek and gum) versus sublingual administration (under the tongue). This visual helps differentiate the two closely related oral mucosal routes.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Routes of Medication Administration as background academic context rather than a clinical decision trigger.
Patient education is a critical nursing responsibility for buccal administration. The nurse must instruct the patient not to swallow the tablet and to avoid eating, drinking, or smoking until it has completely dissolved to ensure proper absorption.
Before administering, the nurse should assess the patient's oral mucosa for any sores or irritation, as this could affect drug absorption and cause discomfort. The site of administration should be rotated with each dose.
What if? If a patient has severe mucositis (inflammation and sores in the mouth), the buccal route would be contraindicated. The nurse would need to contact the prescriber to request an alternative route, such as transdermal, intravenous, or rectal, depending on the medication.

How to Approach the Question

First, identify the key anatomical location described in the question: 'the area between the gums and the inner lining of the mouth cheek'.
Next, recall the definitions of the different medication administration routes provided in the options.
Analyze 'sublingual': 'sub' means under, and 'lingual' refers to the tongue. This is incorrect.
Analyze 'buccal': This term relates to the cheek. This matches the description in the question.
Analyze 'intradermal' and 'transdermal': 'Dermal' refers to the skin. Both of these routes involve the skin, not the inside of the mouth. Therefore, they are incorrect.
Conclude that 'buccal administration' is the only term that correctly describes medication placement between the cheek and gum.
